Canada is a country known for its outdoor adventures, but some of the best Canadian escapes are experienced indoors. The country known for its cool temperatures keeps visitors steaming hot with some of the world's best spa retreats.

Summer coming to a close brings on an onslaught of stress, whether it's work, school or the impending cold weather. The only way to truly beat the fall blues is with a relaxing fall getaway to one of these mind-blowing spas across the Great White North.

Spa Ofuro -- Morin-Heights, Quebec

One of the biggest perks of living in Canada is that we're always surrounded by the outdoors -- even when we're at the spa. Spa Ofuro, in picturesque Morin-Heights, Quebec, offers visitors the opportunity to submerge themselves into the wilderness while submerging themselves into hold and cold baths and a wide range of other body treatments. The spa's sauna, steam bath, whirlpool bath and river bath all present their own physical and mental health benefits.

Visitors can soak (or receive treatments) in the daytime or evening hours. But the most tranquil way to experience Spa Ofuro is to spend a night or two in one of the spa's several suites. Experience complete serenity and restoration while listening to cascading mountain streams, breathing the fresh air of the Laurentians and enjoying the unique, pagoda-style architecture of your cozy room.

You don't even have to leave the city to find that much-needed feeling of, "getting away from it all," this fall. Simply spend a day, or several, at the 2,787-square-metre Four Seasons Toronto Spa in downtown Toronto's esteemed Four Seasons Hotel. One of the largest retreats in the city, "The Spa" features 17 treatment rooms, a full salon, two steam rooms, a sunny relaxation pool, a whirlpool and access to the hotel's terrace overlooking the city's skyline. When you're looking for the feeling of being far away, but don't have the time to get away, "The Spa" at the Four Seasons Hotel is the next best thing.

The Spa at Nita Lake Lodge -- Whistler, British Columbia

The fall "shoulder season" means the bustling ski town of Whistler is operating at a much slower pace. It's one of the best times of year to plan a visit to this iconic town nestled in among some of the most picturesque peaks of the Coast Mountains. The Spa at Nita Lake Lodge combines relaxing and rejuvenating treatments with postcard-worthy views Whistler Mountain.

Visitors can enjoy everything from facial treatments and hot stone massages to a eucalyptus steam room, tranquil relaxation lounge and rooftop hot tubs. The Spa uses only the highest-quality organic and sustainably-sourced products and is staffed with some of the country's top therapists, yoga instructors and relaxation experts. There's simply no better way to take in the snowy mountain peaks of Whistler than while sipping a steaming cup of herbal tea in the comfort of an outdoor hot tub.

Lingering summer temperatures coupled with the changing leaves of the golden larch trees and uncrowded hiking and biking trails make planning a fall vacation to Banff an easy decision. There's no better way to sooth your aching muscles after an adventure than at the Fairmont Banff Springs' Willow Stream Spa.

Rated the Top Hotel Spa in Canada by Travel and Leisure Magazine in 2015, the spa's early 1900s-style mineral pool and waterfalls create an atmosphere that has inspired spas around the country and around the globe. This unique retreat harnesses the power of the area's sacred waters and alpine air to create unique healing experiences that are unlike anywhere else in the world.
